See the other thread "Emusic and Dowload Manager" for more details on how I do it.
I use,like you tried, the "Rename Files from Proprieties" and I don't see the problem. After I select all the files, and apply the renaming scheme, when I save, I get the nag screen "update database, yadda yadda yadda" I select "use same answer for all" and the click "move file and update database".
So this part is not too bad for me ( a couple of clicks, to rename whatever # of files you have donwloaded). The nag screen could be less persistent, but it's not bad even now
The thing that I would like to see is an automatic way to get the cover art. Now I have to do it manually (both saving it from Emusic and then edit each album and add the cover art), an THAT is time consuming
Raymond has hinted that a better integration with Emusic is on his way,so I'll look forward to that
